44 44  For the experiments, we'll be using the NAO robot platform, as well as a laptop for the participants to complete the questionnaires on. The questionnaire will be a combination of questions regarding the emotional state of the participants, their interaction with the robot, and the music included in the interaction. Food will be made available to see and measure how much people will eat.

195 195  Hi, we are <NAME> and <NAME> from the TU Delft Socio-Cognitive Engeering course Group 1, thank you for participating in our prototype evaluation experiment. The experiment is being conducted as a part of the TU Delft course on Socio-Cognitive Engineering and aims to evaluate the prototype designed as a part of the course. The evaluated prototype is based on the Nao robot-platform and is intended to improve the wellbeing of people suffering of dementia.

197 -Consuming food and/or water can be a consequence of the interaction between you and the robot. Therefore, we would like to ask you if you have any allergies. If you have a form of Diabetes, please let us know before we start the first part of the experiment. You are strongly encouraged to share any other health conditions that can possibly be relevant to take into account when doing an experiment with robots and food with us.
98 +The experiment will last for approximately 15-20 minutes, and consists of two sections, as well as questionnaires before, between and after the sections. We kindly ask you to act naturally during the experiment and fill the questionnaires truthfully. Remember that we are evaluating the prototypes performance, not yours. You can stop the experiment at any time. For the questionnaires, the questions will be short and simple. We ask you to answer the questions intuitively.

All data excluding the recordings will be anonymised before analysis and storage. The recordings will not be shared with third parties. After the experiment you have the right to ask for information about the collected data and revoke the right to use it. We kindly ask you not to share any information about the experiment with other participants.
